How to free disk space taken up by (ana)conda?

Question

You can free some space with:

conda clean --all

clean Remove unused packages and caches.

Conda already use symlinks when possible for packages. So, not much to improve here, I guess.

Ok, thanks, but I would like to know “not for a specific environment, but in general” – for all environments.

You can list all packages in all envs with a few lines of Python:

import os
import subprocess
for env in os.listdir('/Users/me/miniconda3/envs'):
    subprocess.call(['conda', 'list', '-n', env])
